There are a wide range of improvements in MRI technology since the first published MR image was presented in 1973. Many of the improvements, however, can be attributed to two aspects of MR imaging, increasing field strength and parallel imaging techniques. At The Canine Chiari Institute, we are equipped with the only 3 Tesla MRI in the world dedicated to veterinary imaging and recognize the benefits of better resolution, faster imaging requiring less anesthesia time, and CSF flow studies with each patient.
The magnet is the biggest, most expensive, and influential component of an MRI system. Recent years have been marked by a dramatic movement in clinical imaging from 0.5 T to 3.0 T imaging systems. The advantage of high field magnets clinically translates into improved resolution and shorter acquisition time.
Parallel imaging techniques
Parallel imaging techniques permit the rapid acquisition of whole body images with high spatial resolution providing diagnostic detail in all areas of the image.
Software developments also deserve brief mention. Most systems now have specially designed interfaces which minimize the technical intervention required by the operator and instead rely on the automated selection of imaging protocols based on clinically driven menus. Automation of the examination procedure allows high quality examinations to be performed.
